Ever wondered what a DVD looks like close up? Using a 375nm laser diode and a 140nm photo sensitive coating on a peice 1.6mm thick glass. Small areas are exposed, then developed as the glass spins around under the focused modulated laser beam. This is actually an polaroid image of the master disc which is the inverse of a real DVD.
